To all whom t may concern:

'Be it -known that LfCHAnLEs W. HUB- BARI), a citizen of the United States, residing at Weston, county of Middlesex, State of lvl'assaehusetts, have invented an Improvement in Twistingr and Winding Apparatus, of which the following description, in connection with the accompanying drawing, is n.. specication, like characters on the drawing representing like parts.

This invention relates to a paratus for twistimg1 and windin yarn of t e type illus trated 11i my veo-pen ing application Se. No. 25,086, tiled May 3, 1915, and in my Patent No. 1,232,686, 'dated July 16, 1917, and which comprises a rotatable yarn receiver and a winding head constructed to build up in the yarn receiver a vyarn mass in layers extending transversely to .the axis of rotation.

I`he objects of the present invention are to provide' a simplified apparatus of this type which is capable of high speed operation; to providean improved' means for producing the requisite relative rotary move ment between the winding head and the yarn receiver.; to provide an apparatus in which such requisite relative movement is derived entirely from the rotative movement of the driving' member for the yarn receiver so that, the apparatus can be operated from a single driving; element, und otherwise to improve devices of this nature, all as will be morel full)- hereinafter set forth and then pointed om. in the app=.nded Claims.

ln order to give an understanding of my invention. l have illustrated in the drawings some selected embodiments thereof which atill now be described.

'proper axial position as it is Fig. 6 is a view similar to Fig. but showing a modified form of theinvention.

I have shown at 1 ayarn receiver of the type illustrated in plication and patent, it haying an elongated tubular form; Situated wlthlnA the yarn receiver is a yarn support 2 on which the yarn muss 3 is built up, said yarn sup rt being slidable longitudinally of theljyiare'ceiver as the yarn mass 3 accumulates Thisyern ceiver, and for this purpose is rovided with two friction membersft whic `tien age'the walls .of the warn receiver 'andiwlch are wlllsby s. spring or springs 5. This form of yarn re ceiver support 1s similar-to that illustrated in my Patent No. 1,232,686,abover ferred to.

The yarn receiver 1 is detachab ysecured at its upper end to and is sustained' by a..

driving member 6 by which it is rotated. At its lower end the yarn receiver has' engagemy above-mentioned ep- .support is constructed to have jrietional en gagement with the walls of the-y'arn rement with a step bearing which serves to hold said lower end of the yarn receiver in rotated by the driving member. The step bearing herein illustrated comprises a spindle 7 rotatably.

mounted ina bearing sleeve 8 and sustained on a step 9. The upper end ofthe spindle is provided with a nose -or' projectlon 10 which enters a central aperture 'in the. bottom 1l of the yarn recelver. Sxiid Spindle is, also provided with alange 12 havlng a projection 13 vwhich enters a notch or recess 14 formed in said bottom 11. L)The beari ing member 8 is received in a'jiolder 15 which is slidable vertically in standard or support 16, said holder beigrikeyed 0r splirred to the standard,l as sho'wn at 17. The purpose ot' making the holder 15 `with the step bearing thel'eln vertical-ly movable in the-standard 16 is to provide for lowering the bearing so as to detach it from the yarn receiver when the latter is to-be removed from the machine. The holder 15 is engaged by a resilient arm. 18, theI resiliency of which normally presses the holder 15 uplwardlyiv and which preferably has sufficient resiliency to retain the holder in its elevated 45 e Vwith ayant-delivery slot 30, exten f yarn recei position even when the yarn receiver is supported thereon. The arm 18 is' provided with an extension 19 forming a foot piece adapted to be engaged by the foot of the operator so that when the operator depresses thearm 14, the h older 15 maybe' lowered 'thereby to disengage the bearing 'from the yarn receiver 1. I have provided herein means for positively locking the holder 15 in its elevated or operative position, this locking means being in the form of alock'? ing bar 2O slidably mounted in the standard 16 and' adapted to engagea groove '21 formed in one side of the holder 15. The locking.

bar 20 is provided with the recessed o'rtion 22 which isso shaped thatwhen the ocking bar is moved into a position to bring said vwhich inoloses the Vwinding"head, presently to be desribd,'fand to "the lower Aen'd of,A which the ygrniigeceilver 1 is secured.

The rotation of'the cam 40 ,will 75 j Vthus give the yarn guide 31 its requisite' vibrating movement. The 'mechanism for thus rotating the cam will be presently described.- 1 The device hereinshown also includes 4guide eye 43 through which theyarn 1 5 vpasses vpri'n" to its passage to theyal-"f Vide 31, all as shown in my above-mentionedgia The yarn t is delivered to the e e'43 of the compensating member 42 throng Vthe through .the shaft 23.

Said compensa -is secured to' a' rock shaft 4' bearin '46 formed in the rock aft: is `provided wit grou e` 33. AI have provided hereilba Simp ing'plfnte` '2 9 a rotative/movement *e to 4 he rotative movement of the ceiver, .which mechanism is-actuated from the rotative movement. of'tlre member 6. `Theshaft 23 is provide worm gear 53 fast o'na horizontally-e tei journalf'dl bearings 55 ca'rrilild by a sleeve lwhichf rigid wit Iand consequently rotates--wt he'rdrivi member l"6. The worm therefore .is carriedjbpdly aroun shaft23 w the suming thatithe shaft non-rotative, 'it will be 'Seen rotative movement fof 'lili about the shaft 23' will'a'" rotate on itsfjp\ u'=5ga1$isfas the shaft 23. gear 53' about its own ax -produce the necessary relative movement between the head 33 with its winding plate 29 and theyarn receiver.

In the construction shown in Figs. 1 to 5 5 inclusive, the Worm gear 53 has rigid there` .with a b eveled gear 60 which meshes with a bevel gear 57` journaled on a stud 58 carried by the lower end 59 of the sleeve 56, This v.beveli gear 57 has rigid therewith a apnr gear il meshin with a gear 62 Whih l rigidwith the ghead 33. The gear 62 1s shown as keyed to a hub 63 which is rigid with the head 33. With this constructlon it will be seen that the bevel gear-60 partakesof the rotative movement of the worm 53 and this rotative movement is .com- 'Qmulnicated through the bevel gear 57 and 'earsl and 62 to the head 33 so that-said cad and the windin plate 29 are given a rotative movement re ative to the Vyarn receiver 1. This relative movement is thus derived from the rotative movement of the drivin member 6, thus obviatiri` the necessity o? a separate drive for t e\.winding head.

The rotative movement of the cams and .50 is also securedfrom this relativemovement of the Winding head and driving mem- 'fber 6. The sleeve 56 is provided with an extension 64 which depends into the head 33 and is connected to a gear 65 situated tao-axially with the shaft 23 and v loosely mountedon a sleeve 66 rigid with the head .33. This gear may be connected to the extension 64 in any suitable-way, but I have herein shown for this'purpose a detachable .connection comprisin a finger l'or projection 67 extending from Qt e hub of the gear 65 and engaging a notch 68 formed in the lower '40 end o the extension 64. This gear 65 "meshes .with two gears 69 and -70 that are with the cams 40 and 50, respectively. T e gear 65 willthus rotate with the driving-member 6 and the relative `rotary movewindingh d. will Agive rotative movement tothe gears 69 and. 70 and thus rotate the cams 40 andOfabo'ut their own axes as the winding head rotaates about its axis. -The gearing mechanisinby vwhich the winding cad-is given" a movement-relative lto the driving member andby which the cams 40 and are rotated is .compacta'nd isfsimple in construction. yMoreover,A itl has the adrotative movement-ofthe' driving member 6, thus making a selfcontained mech ism.

The aad 33. is provide with tag wardly-e tending annular flange 471 which making ageari'ng casing: in which lubricant "may be placed" so jhat .the gears/may be thoroughly lubricated.- y

v I havealso provided means for' varying 05 the. rotative movementL between the driving ing the shaft 23 at different speeds, any dement bet'ween the driving member and the vantage that it is operated entirely by the in'closes the. gearing above referred'to., thus.

member with its attached yarn receiver and the .Winding head thereby to rvary the amount of twist put, into the yarn and the speed at which the yarn is wound. I accomplish this herein by providin means for rotating the shaft 23 in one irection orthe other. If the shaft 23 is stationary and-the yarn receiver is rotating at a predetermined speed, then the winding head and yarn receiver will have a predetermined movement relative to each other. If with the same speed of, rotati on of the driving -member 6 the shaft'- 23 is rotated vin one direction, then the relative movement between the driving memberl and the winding head will. be increased, while ifs'aid shaft is rotated in the op o site direction, this relative movement will e decreased. By thus rotatsired relative 'movement between the yarn 85 receiver 1 and' the winding head can be se-Y cured.. vFor thus rotating the shaft 23, I have herein shown aworm 72 formed on a sleeve 73 which is fast to the shaft 23, but. is Aheld from vmovement longitudinally of said shaft by the bearing 24. This worm 72 meshes with and is driven by a worm gear 7 5 on a. shaft 74. The shaft 74 may be rotated by any suitable means adapted to give said shaft rotation in either one direction 9 5 orthe other at any desired speed. When the shaftI 74 isiat rest, then the gear 72 and the shaft 23 will be held stationary, but by rotating the shaft 7 4 in one direction orthe other, the shaft'23 may -be rotated in one 1'00 direction or the other thereby to vary-the rela-tive movement between the yarn receiver and the winding head. j In Fig. 6 I have shown a slightlydiferent 'arrangement of-dilferential gearing :for pro- 105 ducing the relative rotary movement be. tween the winding head an the yarn reeeiver. In this 'embodiment the worm gear 53 which meshes with the worm 52'is fast on a shaft 54 f'which has a., spur `gear80 110 thereon S 'dggear 8 0 meshes with a pinionv 81 on a-sha 8 A4which is suitably journaled in a `bearin formed in the portion 59 of the sleeve 56. his 'shaft-82 has a beveled gear 83 thereon whichmeshes with a bevel gear 115 84 integral with the gle r 62 thatis rigid .with the winding hea Thefoperation of the gearing shownin Fig. 6 is similar' tothat shown in Figs. 3 4 and.. 5, the princip al difference between thel two differential gears being in the location of the bevel gears.

.In order to prevent the yarn from wearing the guide eye-31 ofthe yarn guide, I ave made said eye' somewhat elongated, as

. b een in Fig. `3, and have arranged the arn-delivery slot 30 .at a slight inclination as'will also be seen from Fig. 3. 3 This inclination o e slot will causethe yarn to have a backend-forth traverse longitudinally of .the vguide eye 31 as said yarn guidevibrates., "1am:

' by which it relative rotary movement betweenthe yarn receiverand winding head being \prod'ucedv by differential -gearing which is actuated by 4therotary movement of the driving member.

1 t Further, this gearing is entirely inclosed and can, therefore, be operated in oil or other ,lfiicant The device hasthe further ad-` yiiiitage -that it anbe run ata very high rate of speed without producingl any appreciable-jar or vibration or noise.
